thanks for sharing....i always figured short trips were bad for our cars...but this only proves the point of how finicky these diva cars are to short trips. clearly their test sessions needs to include short trips...or maybe they did and hence the fix. good to hear nothing permanent.

however these short trips can have an impact on the CCV. if the oil cap has yellow mayonnaise build up be very concerned. you can end up with a hydrolocked engine as has happened on the X5s due to plugged CCVs. I recall last year during a deep freeze of -20C for a few days one of the local BMW garages said many customers came in with bad CCVs. not cheap to replace and in worse cases engines would hydrolock from the excessive moisture buildup.
